Validation working so fine but the border of SfTextInputLayout still red even if the errors are gone when I set HasErro property to true,
How can I bind HasErro's value to my validation in ViewModel?, can you give an example please?

OMG, thank you so much, so the converter did the work..
The way you bound HasErro is so brilliant.

By the way I tested many other products but SyncFusion is the best, keep up.

It would much better if I could only bind the HasError value, such as:

       
       
            x:Name="emailInputLayout"
            Grid.Row="3"
            HelperText="Enter your email address"
            Hint="Email" 
            HasError="{Binding isEmailWithError}" >

           
       
            

           
       

I cannot make the above work.
If bool isEmailWithError is True it has error and if false there is no error. 

Is possible to bind this way?

Sorry,

My approach is working. 
I forgot to set INotifyPropertyChanged on isEmailWithError.

Thank you.
